Zinc supports your body’s natural immune response. But zinc deficiency is common, especially in older people.¹ This can contribute to aging-related decline in immune function.^1,2 But zinc supplementation supports aging immune systems, as well as healthy inflammatory and antioxidant responses.^2-5

Other benefits of zinc

Zinc plays other crucial roles in your body as well. It is an essential component of superoxide dismutase, one of your body’s most powerful natural antioxidants. Zinc is required for the activity of over 300 enzymes that carry out essential biochemical reactions in your body.^6,7

Zinc-containing proteins are vital for hormone production and regulate protein and DNA synthesis, as well as thyroid and bone metabolism.^6,8 Zinc helps maintain cardiovascular, thyroid, neurological and vision health, especially for older people.^7,9,10

Powerful dose, low cost

Zinc absorption can be limited, and certain compounds in plant sources and grains can further inhibit absorption.¹¹ That’s why we’ve combined highly bioavailable OptiZinc® with zinc citrate to provide a potent 50 milligram dose of zinc.

OptiZinc® is a superior bioavailable form of zinc.^12,13 Preclinical studies indicate that it results in higher blood levels compared to other forms of zinc.¹⁴
